Discussion :: Steam Nozzles and Turbines - Section 3 (Q.No.15)
|Tapan Majumder said: (Nov 28, 2013)|
|Blade velocity = v(1)*cos(alpfa).
v1 = steam velocity at the exit of the nozzle.
v1 = 320/cos(30) = 640/(root3).

|U/v = cos α for reaction turbine (parson).|
|Raju said: (Sep 19, 2017)|
|Explain the answer clearly.|
|Rupesh said: (Dec 9, 2018)|
|u/v=cos α so u has value 320; α= 30.
320/v= cos 30.

|Here it is said that exit velocity of rotor, not nozzle so Option B is correct.|
|Biprojit said: (Apr 25, 2020)|
|Stream velocity at exit of rotor =Vr (2) = V1 and vane angle at outlet = inlet nozzle angle according to conditions of 50% rxn turbine.|
